Installing a shower valve using SharkBite plumbing connectors is easier than using traditional plumbing connection methods. SharkBite is a registered trademark for a connection system that joins different pipe types in various combinations. By pushing the fittings onto the pipe, it creates a watertight seal that eliminates soldering, threading, clamping or gluing common with traditional plumbing fittings. It has simplified plumbing repairs for the average homeowner.
Place the shower valve in a suitable location in the control wall. Follow the manufacturer's instructions to determine the proper set back and valve position.
Mount the shower valve. Screw it to a wood block placed between two studs. It is important to refer to the instructions for proper positioning and installation.
Install the Sharkbite fittings onto the shower valve body. Most shower valves have a threaded fitting for the hot, cold, shower and tub spout. Thread the fittings onto the threaded outlets on the valve body. The fittings are threaded on one side and are push to fit on the opposite end.
Apply Teflon tape or pipe dope to the threads on the valve body to provide a watertight seal. Tighten the fittings using an adjustable wrench or pliers.
Install the Sharkbite couplings onto each of the water, shower and tub spout supply lines. Push the fittings onto each end of the pipe until fully seated by inserting the end of the supply line at least a 1/2 inch into the Sharkbite fitting.
Measure the distance from the end of the supply lines, tub spout and shower head using a tape measure. Cut pieces of pipe, usually copper or CPVC, between the existing pipes and the fittings on the shower valve using a hacksaw. Remove burrs from the cut pipe using a piece of sandpaper.
Install the lengths of pipe into the Sharkbite fittings on the shower valve and supply lines by pushing them into each fitting.
